In this study, a wrist protector was manufactured and designed using 3D printing technology to prevent wrist pain when riding a bicycle with a high forward-tilted saddle. The efficiency of the design was analyzed in objective and subjective evaluations. First, seven women in their twenties selected their most preferred design by subjective evaluation from among three 3D wrist protectors. Then electromyography (EMG) was measured and subjective sensations were evaluated while wearing and not wearing the preferred 3D wrist protector as selected by cyclists. Experimental results showed that a wrist-bending angle of 30 degrees was most favored. When the 3D wrist protector was worn, muscle activity was smaller at the flexor carpus radialis position than when the 3D wrist protector was not worn; muscle fatigue was also lower. In the subjective evaluation, the 3D wrist protector was more comfortable than no protector, and wrist fatigue was also lower. In addition, the wrist protector was rated positively for its design suitability, size adequacy, ease of operation, and fit; however, cyclists felt that a little more cushioning was needed.

There may be some problems in size fitness for ready-made-clothes purchasers with Obese body shape. The purpose of this study was to improve the wearing comfort of Junior-High School Girls' slacks by setting grading points and developing grading rules proper to the obesity. The subjects in this study was over 23 kg/m2 of the BMI. The subjects were 124 Junior-High School Girls of 12 to 14 year-old. The results of this study are as follows: (1) The size intervals of waist girth and hip girth were 3 cm and 4 cm respectively. The sizing system, which had frequencies more than 5%, was classified 8 cases. The majority segment is 76-97 size accounting for the 11.29% of subjects. (2) The measurements on 8 size from two groups after drawing slacks pattern on them revealed that the changed values of slacks front and back on the grading point marked are differ, indicating that it is needed to apply body shape. (3) The evaluation on the appearance for wearing slacks showed relatively high score, indicating that the grading between sizes within each group was effective. The studies on the body size distribution on each obesity pattern and on the setting size system reflecting characteristics of each body shape should be performed continuously.

Functions of interlinings to the shell fabric are to improve the garment formability for a beautiful silhouette and elastic potential to the deformed fabric during wearing, and also are to enhance appearance and wearing properties of garment. The objective of this study is to analyse the thermal properties of nonwoven fusible interlining to the thin worsted fabric with various fabric structural parameters. For the purpose fo this study, eight specimens with various weft yarn twists and weft densities of thin worsted fabrics are prepared. Three nonwoven fusible interlinings with different structure which were made by Nylon/Polyester were used for adhering to the thin worsted fabrics. Thermal properties of these 24 adhesive fabrics fused with 3 nonwoven interlinings are measured by KES-F7 System for analysing the thermal suitability of nonwoven fusible interlinings to the thin worsted fabrics with various fabric structural parameters. And air permeability, which was measured by KES-F8-API, of 24 nonwoven adhesive interlining fabrics was also analysed and discussed with the various kinds of nonwoven interlinings and fabric structural parameters.

This study was intended to investigate the wearing conditions of shirts, and examine the preferred subjective sensation for shirt fabrics. A questionnaire survey was conducted on 469 university students (male students $45.3\%$, female students $54.7\%$) in the Cheongju area, Korea. Frequency, descriptive analysis, $\x^2$ and t-tests were used for data analysis. The results were as follows: Regardless of gender, most owned 4 shirts in the autumn, which were each worn once or twice week. Generally, patterned shirts were less favored than those with solid colors, regardless of gender, but the color of the shirts differed slightly according to gender. Most students gathered items from those displayed in the store as their source of information on shirts, and tended to purchase items worth $30,000\~50,000$ won at franchised stores with friends of the same gender. They almost always looked carefully at the size and brand, but the care label and fiber content were rather neglected during the purchase. While purchasing their shirts, the following elements were considered, in this order of importance: size; color; fitness; comfort; price; tactile sensation. Light, dense, soft, warm, wrinkle-free, dry and strong sensation of the shirt fabrics were the strongest preferences for a purchase. There were partially significant gender differences in the subjective sensation of shirt fabrics.

This study analyzed firefighter's actual wearing condition of turnout gear The results are as fellows: 1. When a firefighter is employed, Korea applies only the minimum of firefighters stature and weight but America applies both the minimum and the maximum. The choice of size is highly related with stature more than chest circumference. 2. The satisfaction degree of thermal barrier is very low, 3%. They used rubber gloves rather than heatproof gloves. This is more serious in small country like 'up', 'myun' than in cities. For laundering, they used sprinkling method with firefighting hose. Firefigthers hoped that their clothes could be classified tv the seasons and fire places. 3. frefighter had high unsatisfaction with the movement of hands and leges in the aspect of movement adjustability, air permeability, weight, body temperature regulation, and breathing in the hygenic aspect, fire resistance, thermal resistance property, water proof, chemical reactivity and electrical conductivity. Thev were also unsatisfied with water proof boots and gloves. They were generally satisfied with helmets but firefighters over 90kg of weight were rather unsatisfied. 4. The satisfaction degree for physical fitness was very low and the items with which they were not satisfied depend on physical features. 5. To develop turnout gear, they wanted changes in design, material and size. Reflection tape need to be replaced with high quality products and they wanted the use of velcro and zipper in fastening system.

Purpose: The purpose of this study was to evaluate pressure distribution on the foot with the use of custom made foot orthosis and evaluate influential factors in young people using custom orthosis. Materials and Methods: 22 individuals comprised of young males and females were evaluated by radiograph, pedobarograph, and satisfaction rate and VAS score. The data was analyzed statistically to find influential factors for satisfaction after wearing the foot orthosis. Results: Around 50% of participants were satisfied in wearing the custom made foot orthosis. Initial VAS score of satisfaction of $36.2{\pm}19.7$ improved to $73.1{\pm}15.6$ after application of foot orthosis. There was a statistically significant difference. Talo-second metatarsal angle on AP radiograph after orthosis application was significantly related to satisfaction. On analysis of pedobarograph data, total contact area was increased and weight distribution was transferred medially on ambulation with the orthosis applied. Conclusion: Before designing the foot orthosis, individual foot factors such as foot anatomy and foot pressure distribution should be evaluated for foot comfort and better patient satisfaction.
